Each controller 210 may individually control an air conditioner for controlling and adjusting the operation state of the air conditioner.
The following may describe portions of embodiments of the air conditioning system 200 in more detail in conjunction with portions of embodiments of the method.
Referring to fig. 4, fig. 4 is a flowchart of a data transmission method for an air conditioning system according to an embodiment of the present invention, where the method is applied to an mth controller in the air conditioning system, M is any integer between 1 and M, and the method includes the following steps:
step S110: and receiving a control instruction broadcast by the transceiving terminal or other controllers.
When the air-conditioning equipment is controlled, a server or other controllers send control instructions to the mth controller, the control instructions sent by the server are sent to a transmitting-receiving terminal firstly, the transmitting-receiving terminal broadcasts and sends the control instructions to each controller, and the M controllers communicate through a network, so the control instructions sent by the M controllers are sent in a broadcasting mode. The control instruction may carry related control information for controlling the air conditioning device correspondingly controlled by the mth controller, such as temperature control information or mode adjustment information, so that the mth controller receives the control instruction broadcast by the transceiver terminal or other controllers.
Step S120: and when the control information corresponding to the mth controller is detected in the control instruction, acquiring the control information corresponding to the mth controller.
Step S130: and deleting the control information corresponding to the mth controller from the control instruction to obtain an adjusted control instruction.
If the mth controller detects that the control instruction has the corresponding control information, the mth controller acquires the control information, and can control the corresponding air conditioning equipment according to the control information. In order to reduce the data amount of the data in the transmission process, after the mth controller deletes the corresponding control information from the control instruction, the remaining control instruction for deleting the control information, that is, the adjusted control instruction, is obtained, that is, the adjusted control instruction does not have the control information corresponding to the mth controller.
Step S140: broadcasting the adjusted control instruction.
The mth controller can broadcast the adjusted control instruction, so that other controllers can receive the adjusted control instruction, then other controllers acquire own control information from the adjusted control instruction, delete own control information from the adjusted control instruction, and send the control instruction to other controllers, therefore, the information in the control instruction is gradually reduced in the transmission process, and useless data is prevented from being continuously transmitted and occupying transmission resources.
In addition, when the controller broadcasts the control command, it is another controller that transmits the control command in its broadcast range, for example, when M is 6, each controller forms a networking structure as shown in fig. 3 when networking is performed, only the controller in room X is in the broadcast range of the transceiver terminal, only the controller in room D and the controller in room B are in the controller range of room C, after the room C receives the control command from room D, it is detected whether there is control information corresponding to the controller in room C, when it is detected that there is control information corresponding to the controller in room C, the control information is acquired, and the control information is deleted from the received control command, and the adjusted control command is acquired; finally, the controller in room C broadcasts the adjusted control command. The controllers within the broadcast range of the controller of room C include the controller of room B and the controller of room D. For the controller of the room B, the same flow as that of the controller of the room C is performed. As for the controller of room D, the received control instruction from the controller of room C does not include the control information corresponding to the controller of room D, and therefore, the controller of room D does not broadcast the control instruction any more.
Therefore, in the embodiment, after the controller deletes the control information corresponding to the controller from the received control instruction, the obtained adjusted control instruction is broadcasted, so that data is reduced more and more in the transmission process, useless data is prevented from being continuously transmitted, a server is not required to issue control instructions containing control information corresponding to a plurality of controllers for a plurality of times, the data transmission pressure in the air conditioning system is reduced, and the data transmission efficiency is improved.
In addition, each controller controls one air conditioner correspondingly, and the controller can adjust the temperature, the air output and the like of the air conditioner, so the control information can also comprise temperature control information, namely after the mth controller obtains the corresponding control information from the control instruction, the mth controller can obtain the temperature control information from the control information, and then the air conditioner correspondingly controlled by the mth controller is controlled according to the temperature control information.
Specifically, the mth controller may obtain a current required temperature value from the temperature control information, compare the current required temperature value with a current temperature value displayed by the air conditioning equipment to obtain a first temperature difference value, determine whether the first temperature difference value is within a first preset temperature fluctuation range, and control the air conditioning equipment according to the temperature control information if the first temperature difference value is not within the first preset temperature fluctuation range.
If m is 1, the current temperature value displayed by the air conditioning equipment correspondingly controlled by the controller 1 is 27 ℃, the current required temperature value in the temperature control information is 23 ℃, and the first preset temperature fluctuation range is (-3 ℃), obviously, the first temperature difference value between the current required temperature value and the current temperature value displayed by the air conditioning equipment is not in the first preset fluctuation range, that is, the temperature deviation between the current required temperature value and the current temperature value displayed by the air conditioning equipment is larger than the first preset temperature fluctuation range, the deviation is considered to be strong, the air conditioning equipment is controlled according to the temperature control information, that is, the current temperature value displayed by the air conditioning equipment is controlled to be adjusted to be the current required temperature value, and if the temperature of 27 ℃ is adjusted to be 23 ℃.
In addition, if the first temperature difference value is in the first preset temperature fluctuation range, acquiring current temperature values displayed by M-1 air conditioners left after the air conditioners correspondingly controlled by the mth controller, wherein each controller correspondingly controls one air conditioner, then calculating a first average temperature value of the current temperature values displayed by the M-1 air conditioners, then calculating a second temperature difference value between the first average temperature value and the current temperature value displayed by the air conditioners correspondingly controlled by the mth controller, judging whether the second temperature difference value is in a second preset temperature fluctuation range, and if so, controlling the air conditioners correspondingly controlled by the mth controller according to the first average temperature value.
For example, if M is 6, M is 1, that is, the remaining M-1 air conditioners are the remaining 5 air conditioners, that is, when the current temperature displayed by the air conditioner correspondingly controlled by the 1 st controller is 27 ℃, the current required temperature value in the temperature control information is 25 ℃, and the first preset temperature fluctuation range is (-3 ℃ to 3 ℃), that is, the first temperature difference is within the first preset temperature fluctuation range, therefore, the first average temperature value of the remaining 5 air conditioners is calculated, for example, the first average temperature value is 26 ℃, then the second temperature difference between the first average temperature value and the current temperature value displayed by the air conditioner correspondingly controlled by the 1 st controller is obtained, that is, the second temperature difference is 1 ℃, then whether the second temperature difference is within the second preset temperature fluctuation range, for example, the second preset temperature fluctuation range is (-1.5 ℃ to 1.5 ℃), at this time, the air-conditioning equipment correspondingly controlled by the 1 st controller can be controlled according to the first average temperature difference, that is, the 1 st controller adjusts the current temperature value displayed by the correspondingly controlled air-conditioning equipment to 26 ℃.
In addition, when the second temperature difference is not within the second preset temperature dialing range, the air-conditioning equipment correspondingly controlled by the mth controller is controlled according to the first average temperature value and a second average temperature value of the current temperature value displayed by the air-conditioning equipment correspondingly controlled by the mth controller, for example, the first average temperature value is 25 ℃, the current temperature value displayed by the air-conditioning equipment correspondingly controlled by the 1 st controller is 27 ℃, the second average temperature value is 26 ℃, and the current temperature value of the air-conditioning equipment correspondingly controlled by the 1 st controller can be adjusted to 26 ℃.
Therefore, when the temperature of the plurality of air conditioning equipment is adjusted, the temperature of other air conditioning equipment can be referred to, so that the temperature of the air conditioning equipment can be controlled, the air conditioning equipment does not need to be controlled independently, and the effective energy saving is realized.
In an optional implementation manner, before the above steps are performed, that is, before receiving a control instruction broadcast by a transceiver terminal or another controller, ad hoc networking needs to be performed on M controllers, and a specific process thereof is as follows: and the mth controller detects whether data transmission exists in a data transmission channel between the mth controller and the server, if not, the characteristic information of the mth controller is sent to the server, and the process is repeated until the server receives the characteristic information sent by the M controllers, so that the server performs ad hoc networking on the M controllers according to the sending sequence given to the received characteristic information sent by the M controllers.
It can be understood that, first, the server is connected to the transceiver terminal, the transceiver terminal is connected to each controller, and each controller is not connected, so if M controllers want to perform ad hoc networking, the mth controller needs to monitor whether data transmission is performed on a data transmission channel between the mth controller and the server, if data transmission is performed, it indicates that other controllers may be performing data transmission with the server, and if data transmission is not performed, the server can send its own characteristic information, which can effectively reduce wireless data collision. The characteristic information comprises a serial number, the actual temperature of the environment, a data sending period, a space serial number, a winter and summer mode displayed by the correspondingly controlled air conditioning equipment, a current temperature value displayed by the correspondingly controlled air conditioning equipment and the like.
After the networking is carried out in the mode, the increase and decrease of the nodes can be flexibly carried out, after each controller receives a control instruction, the control information of each controller is extracted, then the control information of each controller is deleted, and then the control information is continuously sent out, so that the complete wireless data interaction process can be realized, the transmission of useless data can be effectively avoided, and the data transmission efficiency is improved.
